Letters Patent No. 91,570, dated June 22, 1869.

BOOK-COVEAR PROTECTOR.

.. Memo-* The Schedule referred to in these Letters Patent and `makingpart ofthe same.

Toll whom it may concern:

Be it known that I, ALFRED L. SEWELL,'of the city of Chicago, iu thelcounty of Cook, and State of Illinois, have invented a certain newv anduseful Device for Protecting the Corners of Books during transportation;and I do hereby declare that the following is va full, clear, and exactdescription'thereof', reference being had to the accompanying drawings,making a partof this specication, inV which Figure 1 represents a book,with my device applied;

Figure 2 represents one .foi-m, detached;

Figure 3, another form, detached;

Figure 4, a blank cut for bending into theforms A and B' Figiire 5, ablank cut for forming D and Figure 6, a blank cut for bending into theform shown at 0of fig. 1.

The nature o i' my invention consists in constructing'a small, light,and stiff device to t over the corners of books, to prevent injuringthem when transported singly by mail, express, or otherwise, or in smallpackages.

It usually happens, from the rough handling' thatl books receive, orfrom heavy weights being placed on them, that the corners of thecoversor'lids are crushed or broken down, so as to be permanently injured.This, sometimes, also happens inl-storage, as vell as in transit, anddetracts much fmm the value o f the books'.

My device overcomes these difficulties, by providing a stilf support forthe outer edges of the covers,.which shall extend farenough on to thecover of the book to v make the support certain, and, by carrying itaround the corners, it also operates as a guard, so that by itsapplication books maybe transported with safety in paper wrappings,which is especially desirable `when sending books b v mail.l

there.

' I first out them out in blanks, as shown at figs. ,4,

5, and 6, and then bend them as indicated by the dot ted lines.

Those shown at A and B,- of iig. 1, are cut as shown at iig. 4, themain' diii'erence between' them being that one is soldered and the othernot.

When they are soldered, the wings or braces E may be made of separatepieces if desired; but they will usually be t'o'und suiiicieut to answerthe purpose with-- out soldering, when out as shown vat tig. 4. Whensoldered, this makes the strongest form shown.

A very simple form 'iss'hown at straight piece, with a slit, b, in eachside, so that when bent, the inner ends of' the flanges or wings F willcross each other, making it very convenient for soldering, 'if thatshould be desired.

Another simple iform is shown atD, where the sides are cutout at a, soas to form a mitred joint when bent. l

In use, the blanks may be kept on hand and bent as required for use, orthey may be fully completed.

Except in cases of'linely-bonnd books, or when they have a long distanceto go, I do not'usually apply my support to the b/acks, as theyare notso much needed The leaves of the book will, to a considerable extent,support the covers, and they are not as liablel to be broken atthatpoint.

I have found, by experiments, that bound books may be transmitted bymail or otherwise, in paper wrappers, without injury, by the use ofthese supports.

Having thus fully described my invention,

What I claim, isv v A metallic protector for book-corners, constructedsubstantially as herein clasping the'opposite corners ofthe book-covers,and

covering the corners of the leaves intervening, and

also for the 'phrpose of being attached and removed when desired, as setforth.
